I usually don't bring up chemtrails with people who aren't aware...it rarely ever seems to go ever well.

At least there with the whole mercury fillings issue most people are aware that mercury is toxic...they just usually aren't aware that is in all silver fillings.

A surprising amount of people around here (Southern California) are aware of chemtrails.

I personally started noticing the weird patterns in the sky and the fact that the clouds looked fake and unlike clouds I looked at when I was younger. I actually learned about HAARP before i learned about chemtrails so it wasn't very surprising.
